添加cookie

   Cookie addMyCookie = new Cookie("usID",234234);  

    addMyCookie.setMaxAge(-1); //  60*60*24*365 cookie 的对大有效期，秒为单位

1. addMyCookie.setDomain("XXXX.com");   
2. addMyCookie.setPath("/");   
3. response.addCookie(addMyCookie);  

//----------------------------------------------------------

public class CookieValue
{
              private CookieValue()
              {}
              public string username;
              public string usercard;
              public string userid

              public static CookieValue   GetInstanceFromCookie(string cookiename)
              {
                        CookieValue value = null;
                        HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiename];
                        if(cookie != null)
                        {
                                  value = new CookieValue();
                                  value.username = cookie.Values[ "username "];
                                  ......以下相同复制另两个字段
                                  return value;
                        }
                        return value;
              }
}

---------调用
CookieValue value = CookieValue.GetInstanceFromCookie(cookie名);

//---------------------------------------------------------------

Cookie[] cookies = request.getCookies();
    if (cookies != null){
           for(int i=0;i
                   Cookie c = cookies[i];
                   if(c.getName().equals("usID")){
                       checkCookie = true;
            }
     }
